Disentangling Multitrophic Interactions: How Vegetation Cover, Wild Boar, Deer, and Predators Shape Rodents Activity and Acorn Dispersal

Integrative Zoology, EarlyView.
Vegetation cover promotes rodent activity and acorn dispersal, while wild boars exert a direct negative effect on mice. Conversely, deer and predators displayed no significant impact on rodent behavior. These results identify wild boars as the main disruptors of rodent‐mediated forest regeneration.
